'The application to Diesel-motorsot loading-compressors, which aredriven on by ture marine boats the arrangement of the aggregates is verydiflicult owing partly to the use to nearly the full hold of said shipsand partly to the strong radiating heat of the turbines. i V V Theobject of the invention is to clear away said dlificulties by arrangingthe turblne'and the compressor entirely or partially outside .the shellof the boat, but by so doing attention must be paid toseveraljrequirements,

It is first of all necessary to introduce the exhaust gases in a hotstate into the turbine,

hence the usual cooling of the exhaust pipe inboard is no longeradmissible. is of importance to make the pipes as short as possible.Further, a strong transmission of heatto the wall of the ship. shouldbe.

thoroughly prevented. Moreover the hot turbine cannot support, at leastnot in the structures known hitherto, the quick cooling when 7 the boatplunges, in case the turbine is arranged unsheltered outboard and hasbeerfi I f show the arrangement of the turbineA with operating untiljust before the plunge. the latter is wanted a cover is required, beingable to resist pressure and which can be shut ofli' against the outerwater and is cooled by water, according to what has been stated above,there where it penetrates the body of the boat.

Vith a structure, however, which meets the requirements with respect tothe resistance against pressure and especially to the stuffing, a freearrangement outboard is admissible, if care be'taken that by means ofproper stop cocks the turbine may be put out of operation in good timebefore the plunge.

The space of time between the putting out of operation and the plungecan be shortened by lowering the temperature of the turbine morepromptly than by'the radiating of heat by means of water e. g. bysprinkling. The possibilities of the realization ofthe'aioresaid ideaare by way of example represented in the Figures 1-8 inclusively of theaccompanying drawings.

Moreover Fig. 5 shows 7 in which manner by closing thestop "cocks N O P Q and opening the'sto'ck cock R the turbine may be putout of operation. The exhaust gases of the turbine then arrive in theatmos-ri phere through theconduit S.

If it is desirable to relinquish a covering 7 ous. By means of thearrangements of the;

stop-cocks, described in connection with Fig.1

exhaust gases of the turbine are carried- .7 5, some time before theintended plunge, the

through the conduit S and the stuifing box into the atmosphere. At thesame time the turbine is sprinkled with cooling Water by means of acooling hose T which is provided with apertures, the turbine being tothis end provided with a revetment U which is not able to resistpressure. The turbine is then cooled slowly and the plunge will not beprejudicial. If the cooling arrangement is 10 to be omitted, theoperation of the turbine should be stopped much sooner so that the sameis cooled naturally by the surrounding atmosphere and when plungingitmay .be considered sufiiciently cooled.

Fig. 7 and the side View in Fig.8 show an arrangement of the compressorCinboard next to the Diesel motor E, whilst the turbine A, which iscooled by the atmosphere, is placed outboard. This arrangement is chosenif itis desirable to protect the staff of the boat against thetransmission of heat and if for the avoidance of long air ways it bebetter to place the compressor near by the Diesel motor.

What I claim is 1. In a submarine boat, turbines, impelled by theexhaust gases of Diesel motors, and compressors, both the turbines andcompressors being arranged outboard.

2. In a submarine boat, turbines, impelled by the exhaust gases ofDiesel motors, and compressors, both the turbines and compressors beingarranged outboard and being surrounded Jointly or separately by amantling 5 which is able to resist pressure and which can be shut oiiagainst the outer water.

3. In a submarine boat, turbines, impelled by the exhaust gases ofDiesel motors, and compressors, both coated with a cover which is notable to resist pressure, but provided with an exhaust pipe which isprovided with mantlings and stop cocks for putting the turbine out ofoperation whilst the Diesel motors remain operating without loading.

4. In a submarine boat, turbines, impelled by the exhaust gases ofDiesel motors, and compressors, and provided with cooling de- Vices tocool the turbine more promptly.

5. In a submarine boat, turbines, impelled by the exhaust gases ofDiesel motors, and compressors, of which only the turbines are arrangedoutboard.

In testimony whereof I have signed my name to this specification.
